IMPROVEMENT IN APPARATUS FOR LIGHTING GAS BY ELECTRICITY.

The Schedule referred to' in these, Letters Patent and making part of the same To all whom it may concern Be it known that I, WILLIAM H. KELLY, of the city, county, and State of New York,'have invented a new and useful Improvement in Electric Lighters, of which the following is a specification, reference being bad to the accompanying drawings. i

Nature and Objects of tho I nocnt'ton. My invention relates to providing a gas-cock'of ordinary construction with a circular out of non-conducting material,which is attached to the end of the shait or base of the gas-cock by means of a screw, and so arranged as to work conjointly with the cock. This nut is provided with a wedge-shaped piece, of conducting material, dovetailedvertically in the nut, and having an angular base somewhat shorter than the. height of the interior circular portion of the nut. The cone or point of this wedge-shaped piece forms a part of and is flush with the exterior circumference of the nut. The angular base serves as a guide, and is receivedinto the groove or recess of an axle having a circular foot, the diameter of which is nearly equal to that of the interior of the nut, above which foot is a groove or recess, and above that a circular projecting shoulder, of the same dimensions as the foot of the axle, upon which is superposed an angular cap or top. A conductingwire passes from the lower surface of the foot of the. axle, exposing itself on the circumference of the groove th erect, and passing upward over the top of axle, where it forms a loop or arch to receive an insulated wire,

connected with a galvanicbattery. The conductingwire passes downward on the opposite side of the axle, in the same manner as above desciibed. The nut is also provided with a sliding band of conducting material, having a projection perforated to receive the wire forming the connection with the ignite-r. The upper angular extremity of the axle is fitted into a correspending aperture llHt band or strap passing over the axle, preventing it from revolving or moving when the gas-cock is operated and the nut turned. I also provide the gas-tip with a bandliaving horizontal projecting lips on its exteriorcircumference, which are perforated vertically, and situated on opposite sides of the band. 'Thesc perforated lips receive the insulated surface of wire, which passes up the side of and adjacent to, but not touching, the gas-tip, their extremities being provided with material non-fusible by the elect'ric spark, and approach to close proximity in thesame plane, immediately above the vent of the tip. These wires are providedat their lower ends with eyes or loops, to receive, the one the battery wire, the other.

the wire connecting with theband upon the nut.

General Description and Operation.

The gas-cock A, of ordinary construction, has u threaded aperture to receive the screw, which projects downward from the vertical axis of the nut 13, of nonconducting material. By these parts being screwed together, uniformity of movement is secured.

The lower circular edge of B is provided with a flange to support the sliding band E, which has a perforated horizontal lip on its exterior surface, whereto is attached the insulated wire 0, connecting with the loop or eye at the lower extremity of the wire L of the igniter, fig. 8.

A wedge-shaped piece of conducting material, D, is soidovetailed into a vertical slot in the side wall of B as to be flush with the exterior circumference of that part, and hasa shoulder or base, so shortened as to serve for a guide, which projects inward toward the vertical axis of B, and is received intothe groove or recess of the axle 0, being so arranged that it will in certain posit-ions come in contact with the wire F when the nut B is moved. The point or apex of D is in constant contact with the interior circumference of the band E of conducting material.

The axle O of non-conducting substance consists .of

a; circular foot or pedestal, of such diameter as thatthe interior of the hollow cylinder in the center of the part B can easily revolve about it.

Above the foot and below the circular project-ingmon center with the rest of the axle, is an angular top sides of and adjacent to or cap, which fits into an aperture of similar size in the band G, whereby the axle C is kept in a stationary vertical position, and the nutIi is free to revolve about it. A corulncting-wire is arched over the top of the axle G, and passes downward on opposite sides through the material, but exposed upon and flush with the circumierence of thegroove, being so arranged upon the groove that in certain positions, the nut B being moved, it will come in contact with the rear vertical surface of the base of the part I). The insulated battery-wire I is attached at the arch or loop surmountiug the axle.

The ignitcr, fig. 8, consists of two pieces of wire, L L, insulated by any non-conducting substance on the parts H H, scoured together on opposite sides by the vertical bands or lips K K of the band J, which fit upon the gas-tip a proper distance above its junction with the pipe. These wires pass upward on opposite but not touching the gas-tip. At a proper height they are bent toward each other in the same vertical plane, and immediately above the vent of the gas-tip their upper extremities are furnished with material non-fusible by the electric spark, and are situated directly opposite each other at such distance as to allow an easy passage of the spark from one point to the other, and directly through the gas when issuing from the vent. The lower ends of the wires are furnished with loops to receive insulated wires, one of which connects with the handE, the other with that pole of the battery opposite the one to which the wire P is attached.

The operation of igniting the gas is peribrmed as follows Turn the thumb-piece of the gas-cock A. about onethirdoi its sweep. This allows the gas free exit from "the vent, and, at thesame time, moves the nut- B, so

that the part D is brought into such position as that the rc'ar surface of its base comes in the'wire 1*, as shown by fig. ti. At the. same time, its apex touches the interior periphery of the band E, the electric current passes from the battery upon the insulated wire 1? to the arch ofthe wire F; down this to the 7 point of contact with 1),through this to the handE and thence upon the wire 0 to the point of the igniting-wire L, to which it is attacluui; and as the opposite point is charged with electricity from an opposite pole, a spark is developed, which, passing from one point to the tip.

other, ignites the gas now issuing from the vent of the In order to break the circuit established as above, turn the thumb-piece of the gas-cock a slight distance further in the same direction as before. This causes the nut B to so more that the base of the part D is carried beyond the point of contact with the wire I as shown by fig. 7, thereby breaking the circuit, but allowing the gas to remain lighted, and its illumination to be increased to the capacity of the burner without again evolving the spark.

C Za/ims.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The not B, of non-conducting materiahprovided with a dovetailed slot to receive the part D, and the cylindrical chamber to receive the axle G, substantially as and for theuses and purposes herein shown and described. I

2. The axle 0 provided with the wire F, substantially as and for the uses and purposes herein shown and described.

3. The part D fitting in the dovetailed slot in the nut B, and so arranged that its'apex is flush with the exterior" circumference of B, and coming in contact with the band E, while the vertical surface of the rear of its base will, at certain pointsin the revolution of the nut B, come in contact; with the wire F, substantially as and for the uses and purposes herein shown and described.

4. The parts B C D in combination with each other, as shown at fig. 5, for the uses and purposes herein shown and described.

5. The parts B O D in combination with the band E and igniter, for the uses and purposes substantially as herein shown and described.

6. The hand G provided with an aperture to receive the angular top or cap of the axle 0, whereby the same is retained in a stationary position when the nut- B is moved.

I n testimony that I claim the foregoing improvements in electric lighters, as above described, I have hereunto set my hand and seal this 16th day of February, 1870.
